Isolation devices are tools used to prevent the transfer of energy or substances between different systems. They are commonly employed in various industries, including manufacturing, healthcare, and laboratories, to ensure safety and maintain control over processes. Examples include valves, switches, and disconnects, which help isolate equipment during maintenance or emergencies. These devices play a crucial role in protecting workers and equipment by minimizing risks associated with unexpected energy release or contamination. By effectively isolating systems, they help maintain operational integrity and compliance with safety regulations, ultimately contributing to a safer working environment.
